working in an intranet sit .downloadString took less than one second,but some times the server is down (maitenance or so on) and the the result took maybe one minute or so.Is there any way to set an lower interval?for example, if the server doesn't respond in 9 seconds return empty string, or so on.
I've read some about async comm but not sure what is the best solution.

I've been testing using WebClient.DownloadString and sometimes I encounter an error: "The remote server returned an error: (403) Forbidden". It is based upon which url I use. For instance, this works:
Dim wc As New Net.WebClientDim strResult As String = String.Empty
Try
strResult = wc.DownloadString("http:/ Obama pages always fails.

I'm working on a project that scrapes data from government websites. I've noticed that whenever I use WebClient it doesn't always get the whole HTML code. Even when I get the robots.txt file it doesn't return everything. For example, http://www.bbc.co.uk/robots.txt has 80 lines but I'm only getting 13 lines.
If an HTML block uses "display: none" in the style I can't get anything between the hidden HTML blocks.Here is the sample code I'm using:[code]...

We need to put a firewall in between our servers and a couple of clients. To do this we need to limit the number DCOM ports available so that we know what ports to open on the firewall.The question I have is do we need to limit the number of ports on all the machines inside the firewall as well as outside. This would cause an issue as we have lots of machines which would need to be modified.If DCOM has the intelligence to negotiate on port 135 which port is available on both machines which need to communicate, we will only need to modify the 2 machines on the outside of the firewall.

I am using a panel control in vb.net (2010) to build a timeline of images. These are very small images (320x180) and I am running into a limit of 240. While the panel does not complain when I add more - it will only scroll to the 240th one.[code]...
I am counting on some of the built-in functionality of the panel in autoscroll mode (being able to bring any of the thumbnails into view), etc. I am certainly not averse to purchasing a third party control for this. I really need to be able to display 1000 or more thumbnails!

I was reading an interesting article here and it made an interesting point about the 'case' statement in vb.net vs the 'switch' statement in C#, which I've pasted below:The following Visual Basic Select Case statement can't be represented in C# with a single switch statement:
Dim Condition As Integer = 55
Select Case Condition
Case 1, 3 To 5, 10, 12, 14, Is > 50
[code]....
I've always found the switch statement in C#, with dropthrough and consequentrequirements for a break in each case, to be a bit unwieldy. Is there any reason they haven't enhanced the switch command to allow these situations? W
EDIT AFTER CLOSE: I'm surprised this was closed, really. With the number of extension methods and helper classes I've found online for other things, I thought an enhanced 'case' would be a good chance. I somewhat hoped a luminary such as Jon Skeet may have commented on the background reasoning, rather than the individuals below who've obviously thought 'religious debate' as soon as more than one language is mentioned.

I want to create a dial which is basically a circle that I can drag around in a circular motion. Ive looked at using the code in an earlier post which allows you to drag items around a screen but I cant figure out how to confine the movement so it only allows the user to drag this circle around in a circular motion. Any coordinate altering I do just looks snappy.

When I go to webcrawler.com and search for something, then look at the source code, a chunk of HTML similar to this displays the search results:
<div id="webResults">
<div class="searchResult webResult">
<a class="resultTitle" data-icl-coi="540" data-icl-cop="results-main" href=[website] target="_blank">[title]</a>
[code]....
But when I use WebClient.DownloadString to read the source code to a textbox, I only get this:
<div id="webResults">
</div>
There's nothing. All of the webresults have been removed.How come I can view the code in my internet browser but not on my application?? I even used an InStr method to confirm that the results weren't contained in the generated code.

I know we can easily limit the number of items in a listbox to be listed. But how to limit the items that are suggested. Like for example, when i type "Co" (using AutoComplete feature ) it will automatically suggest me up to 20 - 30 items that has the word "Co" in it. But i want to limit it to 5 items only. The suggested 5 items, are the top 5 of the list.

I am writing an application that I want to give to a select number of customers.
What is the best solution to use so that after the trail period (1 month) the application will no longer work.
I was thinking that if they are interested in purchasing the software I will give them a license key or something, to unlock the application. However, I would like to make this unique to every computer.
I am have a very limited budget as I am working on my own. So is there any free 3rd party products that does this?
I was thinking of writing the date the application was installed in the system registry, and each time the application loads it will check if this date is over one month. However, the user could turn back the date on their computer.
Another, solution I was to have the application run some many times. For example, the user can only run 30 times. Then it will lock.

I need to hash a number (about 22 digits) and the result length must be less than 12 characters. It can be a number or a mix of characters, and must be unique. (The number entered will be unique too). For example, if the number entered is 000000000000000000001, the result should be something like 2s5As5A62s. I looked at the typical, like MD5, SHA-1, etc., but they give high length results.

I need to know to limit the number of times a radio button can be used. Maybe the number of times the radio button has been used can be stored in an XML file, and when the user wants to reset the counter all they would have to do it delete this file. I really don't know, that's why I'm asking you. But,the program will append a string every time a button is clicked with a radio button selected, I just need to know how to, for instance only allow RadioButton2 to be used in this manner say... 15 times.
